1-1/4" Compact Ball Valve Gray PVC Threaded (1014GT)

The 1014GT is a 1-1/4-inch compact gray PVC ball valve with threaded NPT end connections — a full-port, quarter-turn isolation valve engineered for the industrial, chemical process, water treatment, and commercial mechanical isolation applications where corrosion-free gray PVC construction, compact body format, and threaded NPT end connections at 1-1/4-inch diameter serve the intermediate process line, branch distribution, and individual equipment supply isolation tier of gray PVC industrial and chemical piping systems.

The 1014GT extends the compact gray PVC threaded ball valve series to the 1-1/4-inch intermediate size — the size that holds the same deliberate intermediate hydraulic position in the compact gray PVC ball valve series that 1-1/4-inch occupies across every other valve and fitting family in the Maxx-Supply catalog. Like the 985 stainless steel threaded ball valve, the 1104NL lead-free brass swing check, the 8014GST PVC true union ball check, and every other 1-1/4-inch product in the described catalog, the 1014GT serves the specific intermediate pipe size tier where the hydraulic design of the system produces a 1-1/4-inch sizing result at the isolation valve location — the size that appears when the flow rate, velocity, and pressure drop requirements at a specific branch or equipment supply connection fall between the 1-inch individual connection scale and the 1-1/2-inch secondary distribution scale, and where the isolation valve at that location must match the pipe size precisely without the hydraulic consequences of the wrong size at the intermediate isolation point.

As the 1-1/4-inch counterpart to the 1015GT (1-1/2-inch), 1020GT (2-inch), 1025GT (2-1/2-inch), 1030GT (3-inch), 1040GT (4-inch), and 1060GT (6-inch) in the compact gray PVC threaded ball valve series, the 1014GT fills the intermediate size position between the 1-inch individual connection tier and the 1-1/2-inch secondary distribution tier — providing the correctly sized gray PVC compact ball valve for the intermediate branch, equipment supply, and secondary process line isolation positions in industrial and chemical systems where 1-1/4-inch is the deliberate hydraulic design pipe size at the isolation point.

The 1-1/4-inch position in the gray PVC compact ball valve series serves a buyer profile that is more specialized than the adjacent standard sizes — buyers specifying the 1014GT are working with a confirmed 1-1/4-inch design pipe size, replacing an existing 1-1/4-inch isolation valve in a legacy system, or connecting to a specific equipment connection that is specified at 1-1/4-inch NPT. The 1-1/4-inch size is less frequent in industrial and commercial system valve schedules than the 1-inch and 1-1/2-inch sizes on either side of it — appearing where the hydraulic calculation specifically produces an intermediate sizing result, where existing infrastructure is dimensioned at 1-1/4-inch, or where imported equipment or specific process equipment standards specify 1-1/4-inch NPT as the connection size. The 1014GT is the precision specification for these defined intermediate size requirements — the valve that serves 1-1/4-inch isolation needs exactly as designed without compromise.

The 1014GT and the 1014WT represent the gray and white compact ball valve pair at 1-1/4-inch — where the 1014WT (white, threaded) serves potable water and general-purpose water supply applications where white PVC convention applies, the 1014GT (gray, threaded) serves the industrial process water, chemical service, and gray PVC system applications where gray body convention confirms industrial service specification. Both are the same compact ball valve design at 1-1/4-inch in threaded NPT format — differentiated only by body color and the application convention that color represents. Buyers specifying 1-1/4-inch compact PVC ball valves should select 1014GT for gray PVC industrial and chemical service systems and 1014WT for white PVC potable water and irrigation systems.

The companion relationship between the 1014GT (threaded) and the 1014GS (socket) provides complete end-connection format coverage at 1-1/4-inch gray compact ball valve specification — threaded for equipment connections, existing threaded system replacement, and adapter assemblies; socket for new gray PVC solvent-weld system construction. At 1-1/4-inch, threaded NPT connections are encountered routinely across industrial process equipment connections and existing system replacement applications, and the threaded 1014GT serves both new equipment connection and replacement installation contexts at this intermediate diameter.

Gray PVC construction at 1-1/4-inch delivers the chemical resistance, industrial convention consistency, and corrosion-free service life that define the compact gray PVC ball valve for the chemical processing, industrial process water, and water treatment service environments where the 1014GT serves intermediate branch and equipment supply isolation positions.

Industries & Applications

The 1014GT is the 1-1/4-inch threaded gray PVC compact ball valve specification for full-port quarter-turn isolation across the industrial, chemical, water treatment, and commercial applications where 1-1/4-inch NPT threaded connections and gray PVC construction define the correct intermediate isolation specification:

• Chemical Processing — Intermediate Branch Line & Process Unit Feed Isolation — One-and-a-quarter inch is the intermediate branch size in chemical processing systems where specific flow rate requirements between the 1-inch individual connection scale and the 1-1/2-inch secondary header scale produce 1-1/4-inch sizing at specific branch line and process unit feed isolation points; the 1014GT at 1-1/4-inch intermediate branch and process unit feed isolation positions provides full-port gray PVC isolation with chemical resistance at the direct chemical contact points of intermediate branch line and process unit supply connections where 1-1/4-inch is the hydraulically correct pipe size at the isolation location.
• Water Treatment Plant — Intermediate Chemical Feed Branch Isolation — One-and-a-quarter inch chemical feed branch connections and intermediate process piping isolation in water treatment plant chemical feed systems where specific intermediate-capacity chemical dosing flow rates produce 1-1/4-inch branch sizing between the 1-inch individual injection connection tier and the 1-1/2-inch primary branch tier; the 1014GT at intermediate chemical feed branch isolation positions provides gray PVC full-port isolation at the specific intermediate positions in the treatment plant chemical feed distribution system where 1-1/4-inch is the design pipe size.
• Industrial Process Water — Intermediate Branch Supply & Equipment Connection — Intermediate branch supply connections and individual equipment supply isolation points at 1-1/4-inch on industrial process water systems where specific equipment supply flow rates produce 1-1/4-inch sizing at individual equipment connections feeding from 1-1/2-inch secondary distribution branches; gray PVC compact ball valve isolation at the intermediate equipment supply tier where 1-1/4-inch is the deliberate design pipe size between the secondary distribution scale and the individual instrument connection scale.

• HVAC Hydronic — Intermediate Branch & Equipment Connection Isolation — One-and-a-quarter inch intermediate branch supply connections and individual equipment supply isolation on HVAC chilled water and hydronic heating systems where specific hydraulic flow calculations produce 1-1/4-inch sizing at intermediate branch and individual equipment supply connection isolation points between 1-inch individual connections and 1-1/2-inch secondary distribution; gray PVC compact ball valve isolation at intermediate HVAC hydronic branch positions within PVC material service conditions.
• Industrial Chemical Injection — Intermediate Branch Line Isolation — Isolation at 1-1/4-inch intermediate chemical injection branch connections and individual chemical feed sub-branch supply points on industrial chemical injection systems where specific chemical dosing flow rates produce 1-1/4-inch branch sizing at intermediate injection system distribution points; gray PVC chemical resistance at intermediate chemical injection branch isolation locations where the chemical concentration of the dosing solution at intermediate branch connection points is elevated relative to downstream diluted injection positions.
• Commercial Building — Intermediate Branch Supply Isolation — One-and-a-quarter inch intermediate branch supply connections in commercial building domestic water and gray PVC process water systems where specific hydraulic design calculations produce 1-1/4-inch sizing at intermediate branch isolation points between the secondary 1-1/2-inch distribution tier and the individual 1-inch equipment connection tier; gray PVC compact ball valve isolation at intermediate commercial building branch positions where gray PVC system construction is the system material.
• Agricultural Irrigation — Intermediate Zone Supply Isolation — Isolation at 1-1/4-inch intermediate zone supply connections and sub-main branch isolation points on agricultural and commercial irrigation systems where specific zone supply flow rates produce 1-1/4-inch sizing at intermediate zone distribution isolation points; gray PVC construction handles varied irrigation source water chemistry at intermediate zone supply isolation positions.
• Industrial Aquaculture — Intermediate System Distribution — Full-port isolation at 1-1/4-inch intermediate distribution connections and individual recirculation circuit supply isolation points in recirculating aquaculture systems where specific flow rates at intermediate system positions produce 1-1/4-inch sizing at individual isolation valve locations between the primary distribution tier and the individual equipment connection tier.
